hey guys! I'm new to the creo, currently using creo2. I want to design a plastic cover that has all outter surfaces curved to the outside (convex) because straight surfaces can cause many issues when injection moulding. I attached the file, bellow is the procedure: I used a blend function with top and bottom section - i tried with surface blend + thicken and solid blend + shell I used a boundary blend (surfaces) to create the top curved part (1/4) and then pattern. I tried with surfaces + merge + thicken but it returns an error I tried with solid blend for bottom part and surface + fill + merge + solidify for top and then shell and it also returns an error. I suspect the way I chose to create the top curved part might not be ok, but I ran out of ideas.

hey guys!

I'm new to the creo, currently using creo2. I want to design a plastic cover that has all outter surfaces curved to the outside (convex) because straight surfaces can cause many issues when injection moulding.

I attached the file, bellow is the procedure:

I used a blend function with top and bottom section - i tried with surface blend + thicken and solid blend + shell
I used a boundary blend (surfaces) to create the top curved part (1/4) and then pattern.
I tried with surfaces + merge + thicken but it returns an error
I tried with solid blend for bottom part and surface + fill + merge + solidify for top and then shell and it also returns an error.

I suspect the way I chose to create the top curved part might not be ok, but I ran out of ideas.
